Anthony Giardullo commented on THRIFT-265:
------------------------------------------
I believe the realloc call in TNonBlockingServer should be using 1024 instead
of readBufferSize_.
Also, how about instead of hard coding the limit to 512, we make this value
configurable? (And disabling this feature if the value is set to 0).
> Buffer bloat in TNonblockingServer

> TNonBlockingServer never resets the lengths of the buffers it maintains for
> reading and writing. Servers with a long life and many concurrent
> connections eventually generate an overhead that can reach into the
> gigabytes, particularly in services that have varied message sizes.
